Description Alexander Mezin 2019-05-10 05:13:03 UTC
In game the screen is sometimes too dark, when it shouldn't, sparks everywhere. In menus everything is OK.

Screen capture: https://youtu.be/rr9DdFfII5E (glitches begin at 0:16)

Also reported the issue to game developers, got no response so far.

gpu: RX Vega 64
mesa: 19.0.3, also tested with 19.1 rc1, no changes
linux 5.0
Comment 1 Timothy Arceri 2019-05-27 03:28:17 UTC
What version of LLVM are you using?

I could not reproduce the issue on my Vega 64 with the development version of LLVM 9.0.0.
Comment 2 Alexander Mezin 2019-05-27 04:04:12 UTC
llvm 8.0.0
Comment 3 Timothy Arceri 2019-05-27 04:58:49 UTC
Are you able to test with llvm 9?
Comment 4 Timothy Arceri 2019-05-29 05:33:02 UTC
I've run it on llvm 8 and mesa 19.0.5 and was unable to reproduce the issues seen in the screen capture on my Vega 64.

I won't have time for that until weekend

Just re-tested with mesa 19.0.5+llvm 8, the issue is still there.

It seems to be track-specific. At least it doesn't happen on "Compound", for example.

Also the game runs fine under Proton/SteamPlay (no glitches/artifacts).
